When Swiss-American anthropologist Adolph Bandelier peered into Frijoles Canyon in 1880, guided there by a Pueblo man named Jose Montoya, he was looking at something remarkable: hundreds of rooms carved directly into the soft volcanic rock of the canyon walls, abandoned centuries before but still standing. The cliff dwellings and pueblo ruins of what would become Bandelier National Monument preserve one of the most complete records of Ancestral Puebloan life in the Southwest, set against a landscape sculpted by one of North America's most violent volcanic eruptions. The canyon would later serve a very different kind of history, housing scientists building the atomic bomb.

The monument protects archaeological sites...
